﻿June, 1896.] SYNOPSIS OF THE WEASELS OF NORTH AMERICA. 19 



resemblauce therefore to P. cicognani is mucli less marked in the female 

 icasliingtoni than in the female noveboracensis. 



Beniarlcs. — This new si^ecies is represented in the collection by 14 

 sknlls and 6 skins, of which the greater number are males. The female 

 is darker than the males, and the top of the head is darker anteriorly 

 than the rest of the upper parts, while in the males it is concolor with 

 the back. These differences are probably seasonal, the female not 

 haviDg- completed tlie change from summer to winter pelage, though 

 collected December 11. All are from the Mount Adams region. 



Measurements. — The skins, which are well made, afford the following 

 approximate measurements: Male, total length, 210 5 tail vertebra^, 155 5 

 hind foot, 44. Female, total length, 360 ; tail vertebrse, 120 ; hind foot, 37.

Type locality. — 'Hudsons,' 14 miles north of Tarpon Springs, Fla. 

 Geographic distribution. — Peninsula of Florida; limits of range 

 unknown. 



General characters. — Size rather large, about equaling male of Fnto- 

 ri'us noveboracensis ; skull similar to that of longicanda, but with very 

 large andital bulhe. 



Color. — Upper parts dull chocolate brown, darkest on head; upi^er 

 lip and chin whitish; rest of under parts, including fore feet and toes 

 of hind feet, yellowish ; a brown spot behind corners of mouth; a small 

 tuft of white hairs under anterior root of ear. The color of the under 

 parts covers the belly broadly and is not encroached upon by the color 

 of the upi^er parts. Irregular and inconstant white markings are some- 

 times present between and behind the eyes. 



Cranial characters. — Skull rather massive, resembling that of longi- 

 but with higher sagittal crest; less spreading zygomata; narrower, 

 higher, and more swollen andital bulhie, and less prominent postorbital 

 processes. Contrasted with P. noveboracensis the postorbital constric- 

 tion is deeper, the brain case higher and more subtriangular, the andital 

 bullge higher and more swollen, the upi^er carnassial tooth decidedly 

 larger, and the molar smaller. The upper molar is peculiar : It is short, 

 hardly expanded at either end, and implanted at right angles to the 

 premolar series. 



Measurements. — An adult female from Tarpon Springs, Fla. : Total 

 length, 374; tail vertebrje, 127; hind foot, 44.5.
